WINDOW.

SPECIFICATION forming part of I ietters' Patent No. 626,615, dated June6, 1899'.

l Application filed June 14, 1898. Serial No. 683,412. (No model.)

. To all whom it may concern:

Be it known that 1, JOHN 0. 11001), a citizen of the United States ofAmerica, and a resident of WVilkinsburg,county of Allegheny, and Stateof Pennsylvania, have invented certain new and useful Improvements inWVindows, of which the following is a specification.

Figure I is a vertical section of my improvement applied to the lowersash of a windowframe and showing the upper sash broken away. Fig. II isa horizontal cross-section of the same on line II II of Fig. I. Fig. IIIis a vertical section through the side rail of a window-sash on line IIIIII of Fig. I.

The purposes of my invention, generally stated, are to devise apparatusby which a window-sash or window-sashes may be raised and lowered by theapplication of pneumatic or water or other liquidor gaseous pressure. Afurther purpose of my invention is to seal hermetically the frame of thesash in the window-casing.

'hly invention may be applied to all kinds and variety or windows and toupper, lower, and swinging sashes.

By the use of my invention I'can dispense with sash-weights, althoughthe same may be used, if desired, greatly reduce the labor in raisingand lowering the window, and make by far closer joints between therespective sash and the window-casing than heretofore it has beenpossible to obtain.

In the accompanying drawings,which make part of this specification, 2 isthe top rail of the lower sash. 3 are the side rails of the same sash.

4. is the bottom rail of the sash.

3 3' are the side rails of the top sash.

5 is the bottom sill of the window.

6 G are the side posts of the window.

In the side posts of the window-casing I make a suitable vertical recess6. This re-' cess or groove extends a sufficient distance to fully coverthe movement of the sash. In said recess and at the inner portionthereof I place a rubber or other suitable tube 7. Outside of said tubeis a vertical strip 8, capable of a lateral movement in the recess 6.Partly seated in said recess and partly in a vertical groove 3 of theside bars of the sash is the vertical cylinder 9. In said cylinder 9plays the piston 10, having the piston-rod 10, provided at its upper endwith a pivoting-arm 10",

which is inserted into a suitable socket in the side rail of the sash.

11 is a suitable supply-pipe for feeding the flexible tube 7, while 12is a supply-pipe of the cylinders 9; These pipes are provided withsuitable valves. In the lower windowsill and extending longitudinallythereof is a groove 13. In this is located a suitable rubber or otherflexible air or water tight tube 14, over which is superposed in therecess a movable strip 15. This projects slightly, so as to fit thelongitudinal groove 16 on the under edge of the sash. In the lower partof the top sash and extending across the inner face thereof is anothergroove 17. In said groove is located a light flexible tube 18, againstwhich presses a movable strip 19. To swivel the window, the sash israised slightly and the same is turned on the pivotal arm 10.

In the operation of my device the tubes7 7 are kept constantly inflated.or filled with liquids under pressure. This makes a tight seal betweenthe window-sash and the side posts 6. To raise the window, a suitablevalve is turned, admitting the pressure beneath the piston-head 10, andto lower the window the pressure is released bymanipulating a suitablevalve, exhausting the pressure. The height to which the window is raisedis determined by the amount of air or liquid introduced in the cylinder9, and when the window is at the proper height the valve is turnedclosed, locking the window in position.

If desired, the intermediate strip 8 can be omitted and the tube beardirectly against the cylinder 9 and against the side rail of thewindow-sash, and where the window israised by hand the cylinder 9 may beomitted and the sash bear directly against the tube 7.

Having described my invention, I claim- The combination of awindow-sash; a power cylinder a piston in said cylinder; a pistonrodhaving a pivoting-arm attached to the window-sash; and means foradmitting pressure and releasing pressure in said cylinder for raisingand lowering said sash.

Signed by me at Pittsburg, Pennsylvania, this 11th day of June, A. D.1898.

OHN G. HOOD.
